Description

Technical Field

[0001] The present disclosure relates to the technical field of battery recycling, and in particular to a battery residue filter press device. Background Art

[0002] As a simple and efficient solid-liquid separation equipment, filter press is widely used in petrochemical, food and pharmaceutical, material manufacturing and other fields. It uses hydraulic devices, plates and frames and filter cloths to achieve efficient separation of solids and liquids. Especially in the field of battery recycling, filter press separates slag and liquid during the leaching and impurity removal process. Through the filter press, valuable metal ions can be recovered and impurity ions can be removed.

[0003] On the one hand, the traditional filter press forms filter cake-like materials after filtration. The process of separating materials is to push the plates and frames apart one by one before unloading, which results in the filter cake-like materials falling one by one, making the unloading efficiency of the filter press low. On the other hand, the filter residue after filtration is currently collected through the unloading hopper. Due to the sticky nature of the filter residue, some of the filter residue will adhere to the unloading plate, causing the material to block the unloading hopper, increasing the hopper load, and requiring time and manpower to clean the filter residue, increasing the cost of manual cleaning and unloading, and some larger pieces of filter residue are more likely to cause material blockage during the unloading process.
